- A braiding machine, as shown in
FIGS. 1 and 2 and provided withreference numeral 10, comprises aplatform 12 for supporting an annular row ofmembers 14 for drivingbobbins 16. Themembers 14 extend around a first common axis A and are rotatably movable about second axes B which are substantially parallel to one another and to the first axis A. - The
members 14, which can be seen more clearly inFIG. 3 , each comprise apinion 18, which is meshed withpinions 18 of adjacent members and awheel 20, which comprisesnotches 22 over its circumference that are designed to receive complementary means 24 of thebobbins 16 so as to drive said bobbins about the second axes B. - As can be seen in
FIGS. 6 and 7 , eachbobbin 16 has alower base 26 and an upper coil of wire 28. In this case, thebase 26 comprises twoparallel plates 30, namely an upper plate and a lower plate. Theplates 30 are mutually spaced and interconnected by rods which form said complementary means 24. Thewheel 20 is intended to fit between theplates 30, thenotches 22 in said wheel receiving the rods so as to rotate them (FIG. 3 ). - The
platform 12 comprises means for guiding thebobbins 16, which means comprise, for eachmember 14, a sliding track or annularsliding groove 32 which extends around the second axis B of the corresponding member and is designed to receive at least oneelement 34 for guiding each bobbin so as to guide said bobbin about the second axis B. Each slidingtrack 32 is connected to adjacentsliding tracks 32 by switching means 36 (FIGS. 4 and 5 ) so as to rotate thebobbins 16 about the first axis A by moving the bobbins from one member to the next adjacent member in each case. - The sliding
tracks 32 have to be cleaned regularly so as to remove residual grease and any pieces of wire. In the prior art, this maintenance task is carried out manually, as shown inFIG. 8 . The width of the sliding tracks is relatively narrow and said tracks are currently cleaned by means of a cotton cloth which is moved along the sliding tracks by means of a laboratory spatula, for example. This maintenance operation is time-consuming and cumbersome. In this process, the user handling the spatula is also at high risk of getting injured when moving the cotton cloth along the sliding tracks. - The present invention provides a simple, effective and economical solution to the above-mentioned problem.
- For this purpose, the present invention proposes a method for cleaning a braiding machine, in particular for electrical cables,
- said braiding machine comprising a platform for supporting an annular row of members for driving bobbins, said members extending around a first common axis and being rotatably movable about second axes which are substantially parallel to one another and to said first axis, said members each comprising a pinion, which is meshed with pinions of adjacent members and a wheel which comprises notches over its circumference that are configured to receive complementary means of the bobbins so as to drive said bobbins about said second axes, said platform comprising means for guiding said bobbins, which means comprise, for each member, an annular sliding track which extends around said second axis of the corresponding member and is configured to receive at least one element for guiding each bobbin so as to guide said bobbin about said second axis, each sliding track being connected to adjacent sliding tracks by switching means so as to rotate the bobbins about said first axis by moving the bobbins from one member to the next adjacent member in each case,
- characterised in that said method comprises:
- a step of providing the machine with at least one cleaning tool, said cleaning tool comprising means configured to be received in at least some of the notches in each wheel so as to drive said tool about said second axes, and at least one guide element configured to be received in said sliding tracks so as to move said tool about said first axis, said at least one guide element being configured to drive a means for cleaning said sliding tracks or to be provided with said means, and
- a step of rotating said members in order to drive said tool about said first and second axes.
- The invention therefore proposes using a cleaning tool that is similar to a bobbin such that the machine cooperates with said tool and drives it about the axes as though it were a bobbin. The tool is provided with a guide element which engages with the sliding tracks, as is the case for a bobbin, but is capable of cleaning said tracks by means of a cleaning means. The element preferably has a specific shape which facilitates the driving of the cleaning means and minimises the risk of said means getting stuck in the sliding tracks.
- The method according to the invention may have one or more of the following steps:
- said cleaning means is a cloth, made of cotton for example;
- the method comprises:
-
- a first provision step in which the cleaning tool is mounted on a first of said wheels,
- a first step of rotating said members in order to drive said tool about said first and second axes,
- a second provision step in which the cleaning tool is mounted on a wheel that is adjacent to said first wheel,
- a second step of rotating said members in order to drive said tool about said first and second axes;
- said tool comprises two guide elements, namely a front guide element and a rear guide element, the front guide element being configured to drive said cleaning means or to be provided therewith;
- said tool comprises a base on which said guide elements are mounted such that they are free to rotate about substantially parallel axes;
- said front guide element comprises a truncation for accommodating and driving said cleaning means;
- said truncation defines a surface that is substantially perpendicular to a plane that passes through the axis of rotation of the corresponding element;
- each of said guide elements is generally in the shape of an ogive.
- The present invention further relates to a cleaning tool for carrying out the method as described above, characterised in that it comprises a base comprising means configured to be received in at least some of the notches in each wheel so as to drive said tool about said second axes, said base having at least one guide element configured to be received in said sliding tracks so as to move said tool about said first axis, said at least one guide element being configured to drive a means for cleaning said sliding tracks or to be provided with said means.
- The present invention further relates to a braiding machine, characterised in that it is provided with at least one cleaning tool as described above.
- The invention will be better understood, and other details, features and advantages of the invention will become apparent upon reading the following description, given by way of non-limiting example and with reference to the accompanying drawings, in which:
-
FIG. 1 is a schematic perspective view of a braiding machine, in particular for electrical cables, -
FIG. 2 is a schematic partial perspective view of part of the machine fromFIG. 1 that has bobbins, -
FIG. 3 is a schematic perspective view of a member for driving a bobbin of the machine fromFIG. 1 , -
FIGS. 4 and 5 are schematic views of an annular row of members for driving bobbins of the machine fromFIG. 1 , -
FIGS. 6 and 7 are schematic views of a base of a bobbin, -
FIG. 8 is a schematic perspective view of part of the braiding machine, showing a step of cleaning a sliding track according to the prior art, -
FIG. 9 is a schematic perspective view of a cleaning tool according to the invention, and -
FIG. 10 is a schematic perspective view of part of the braiding machine, showing a step of cleaning a sliding track according to the invention. - Although the
braiding machine 10 fromFIG. 1 has already been described above, it will be described in more detail below. - The
machine 10 comprises a table of which the upper platform forms the above-mentionedplatform 12. Theplatform 12 is substantially horizontal in the example shown. It has acentral chamber 40 which has a vertical axis A and around which the row ofmembers 14 extends. - The
chamber 40 extends upwards from theplatform 12 and has, on its upper end, afirst ring 42 which has a rotational axis A. - A
second ring 44 having the rotational axis A is arranged above thefirst ring 42 and at a distance therefrom so as to allow wires to pass between therings second ring 44 is connected to the upper ends ofvertical rods 48 by means of substantiallyhorizontal bars 46, the lower ends of which rods are attached to theplatform 12. Therods 48, in this case three rods, are uniformly distributed around the axis A. - The
wheel 22 of eachmember 14 is located on top of theplatform 12 and thepinion 18 thereof is located under theplatform 12. Thepinions 18 of themembers 14 are meshed with one another and with an output pinion of amotor 50, which is connected to areduction gear 52 in this case. Themotor 50 rotates afirst member 14 in the clockwise direction (or anticlockwise direction), and this will cause the adjacent members to be driven in the opposite direction. Therefore, as shown schematically by the arrows inFIG. 4 , half of themembers 14 rotate in the clockwise direction and the other half of said members rotate in the anticlockwise direction. - The means for guiding the
bobbins 16 have an annular row ofsectors 54 which are attached to theplatform 12 and each define thesliding track 32 of thecorresponding member 14. Eachsector 54 is formed, in this case, by a metal block in which thetrack 32 is made by means of machining. Thesectors 54 are circumferentially arranged one next to the other around the axis A such that their ends meet, and said sectors comprise, at the circumferential ends thereof,housings 56 for receiving switching means 36. - In the example shown in
FIGS. 4 and 5 , said switching means arediscs 36. At each circumferential end of asector 54, thehousing 56 forms a break in the sliding track. Theswitching disc 36 has two track portions which intersect one another to form an X and connect the circumferential ends of the track of one sector to the circumferential ends of the track of the adjacent sector (FIGS. 4 and 5 ). - Each
bobbin 16 has alower base 26 and an upper coil ofwire 60.FIGS. 6 and 7 show a base 26 which has in particular twoplates 30 placed one on top of the other, namely a lower plate and an upper plate. Theplates 30 have an elliptical or oblong peripheral contour. Said plates are mutually spaced and interconnected by substantiallyvertical rods 62, which can be seen inFIG. 2 . The space between the plates is configured to receive a circumferential portion of thewheel 20 of amember 14, therods 62 being intended to fit in thenotches 22 in thewheel 20. Therods 62 engaging with thenotches 22 and themembers 14 being rotated will result in thebobbins 16 being rotated. - The
upper plate 30 has means 64 for attaching thecoil 60. Thelower plate 30 hascylindrical housings 66 for receiving theguide elements 34 and rotatably guiding said elements about vertical axes C that are parallel to one another. Eachguide element 34 has an uppercylindrical member 68 which fits in the correspondinghousing 66 with small clearances, and alower ogive 70 intended to fit in the slidingtracks 32 and the switchingdiscs 36 and engage therewith so as to rotatably guide thebobbins 16 about the axes A and B. - Each
ogive 70 has an elongate shape and has a central body comprising twolateral surfaces 70 a that are parallel to one another, and a front end and a rear end which taper to a point. Each of these ends has two inclined lateral surfaces 70 b. Finally, eachogive 70 has alower surface 70 c which is substantially perpendicular to the axis C. - The
machine 10 also comprises means for driving or winding up a cable so as to provide a braid or overbraid therearound. Said means are supported by theplatform 12 and have a vertical arm 72 (FIG. 1 ) which has awheel 74 for driving a cable (not shown) about a horizontal axis D, which cable is intended to pass through the inside of thechamber 40 and through aguide band 76 arranged above the tworings platform 12 in storage means 78. - The
braiding machine 10 operates in the following manner. The cable which is to be surrounded by a braid is moved through thechamber 40 and theband 76, from the bottom towards the top, by being driven by thewheel 74. Thebobbins 16 are mounted on thewheels 20, therods 70 of thebases 26 of thebobbins 16 fitting in thenotches 22 in thewheels 20 of themembers 14. The wires on thebobbins 16 pass between therings bobbin 16 is rotated about the axis B by means of amember 14, by engaging with the corresponding slidingtrack 32, and is then moved to a further member so as to rotate about the axis B of said further member, by engaging with the track portion of thedisc 36 located between the members and by means of the sliding track of said further member. Some of thebobbins 16 rotate in the clockwise direction about the axis A and the remainder of the bobbins rotate in the anticlockwise direction about the axis A. - As explained above, the process for cleaning the sliding
tracks 32 is time-consuming and cumbersome because it is carried out manually using acotton cloth 80 and ametal spatula 82 used to move thecloth 80 along the track of each sector and from one track to the next (FIG. 8 ). - The present invention provides a simple, effective and economical solution to this problem, by means of a
cleaning tool 84. -
FIGS. 9 and 10 show an embodiment of thecleaning tool 84 according to the invention. Saidtool 84 has a base 86 that is similar to thebase 26 of abobbin 16, such that the tool can engage with the members and be driven thereby, as explained above. - The
base 86 has twoplates 88 placed one on top of the other, namely a lower plate and an upper plate. Theplates 88 have an elliptical or oblong peripheral contour. Said plates are mutually spaced and interconnected by substantiallyvertical rods 90. The space between the plates is configured to receive a circumferential portion of thewheel 20 of amember 14, therods 90 being intended to fit in thenotches 22 in thewheel 20. Therods 90 engaging with thenotches 22 and themembers 14 being rotated will result in thetool 84 being rotated. - The
upper plate 88 may have means 92 for gripping the tool. As is the case for thebase 26, thelower plate 88 hascylindrical housings 94 for receiving theguide elements 96 and rotatably guiding said elements about vertical axes C that are parallel to one another. Eachguide element 96 has an uppercylindrical member 98 which fits in the correspondinghousing 96 with small clearances, and alower ogive tracks 32 and the switchingdiscs 36 and engage therewith so as to rotatably guide thebobbins 16 about the axes A and B. - The
rear ogive 100 has an elongate shape and has a central body comprising twolateral surfaces 100 a that are parallel to one another, and a front end and a rear end which taper to a point. Each of these ends has two inclined lateral surfaces 100 b. Finally, theogive 100 has alower surface 100 c which is substantially perpendicular to the axis C. - The
front ogive 100′ has an elongate shape and has a central body comprising twolateral surfaces 100 a that are parallel to one another, and a rear end which tapers to a point and has two inclined lateral surfaces 100 b. Theogive 100′ also has alower surface 100 c which is substantially perpendicular to the axis C. - The
ogive 100′ is configured to drive a means for cleaning the slidingtracks 32, for example a piece of cotton or a cotton cloth, or to be provided with said means. In the example shown, the front end of thefront ogive 100′ has a truncation which defines asurface 100 d that is inclined relative to thesurface 100 c and is substantially perpendicular to a longitudinal plane P of theogive 100′ that passes through the axis C thereof. Furthermore, thefront ogive 100′ has a reduced length and is therefore shorter than theogive 100, the front end of said front ogive having a front edge which is rounded, substantially around said axis C. - The
surface 100 d is a surface for bearing and driving the piece ofcotton 80, which is therefore intended for being moved along the slidingtracks 32 so as to clean said tracks as the tool is moved along by means of themembers 14. - The sliding tracks 32 of the
braiding machine 10 can be cleaned in the following manner. At least onetool 84 is mounted on amember 14, therods 90 of thebase 86 of said tool fitting in thenotches 22 in thewheel 20 of saidmember 14. Theogives track 32 and a piece ofcotton 80 is arranged in front of the front ogive and wedged between the bottom of the sliding track and thesurface 100 d of theogive 100′. Thetool 84 is rotated about the axis B by means of themember 14, by engaging with the corresponding slidingtrack 32, and is then moved to a further member so as to rotate about the axis B of said further member, by engaging with the track portion of thedisc 36 located between the members and by means of the sliding track of said further member. Thetool 84 rotates in the clockwise direction (or the anticlockwise direction) about the axis A, and this makes it possible to clean half of the sliding tracks 32. The tool is withdrawn from the member and mounted on a member that is directly adjacent thereto, and the above-mentioned steps are repeated such that thetool 84 rotates in the anticlockwise direction (or clockwise direction) about the axis A, and this makes it possible to clean the other half of the sliding tracks 32.
